This collection focuses on some of Joni's most challenging and visionary work from albums (The Hissing of Summer Lawns, Mingus, Dog Eat Dog and others) that have since proved vastly influential. Including "Sex Kills," "Nothing Can Be Done," "Hejira" and more, selections were drawn from her Reprise, Asylum and Geffen albums spanning 1867-1994. This release, along with the Hits album, mark the first Joni Mitchell compilations ever released.
